Abstract

Dans un moteur à lévitation magnétique, un stator porte une partie moteur entre deux parties palier magnétique, et des culasses de palier magnétique qui constituent les parties palier magnétique sont disposées de manière circonférentielle à intervalles réguliers par rapport à la face latérale d'un rotor à une distance prédéterminée de la face latérale. Chacune des culasses de palier magnétique possède deux pôles saillants faisant face à la face latérale du rotor, un pôle saillant étant entouré d'une bobine pour palier magnétique et l'autre pôle saillant étant équipé d'un premier aimant permanent. Entre chaque pôle saillant fourni sur le côté de la partie moteur et une culasse de moteur de la partie moteur se trouve un second aimant permanent. Tous les pôles saillants de la partie palier magnétique se trouvant du côté de la partie moteur sont entourés d'une bobine pour palier magnétique ou équipés d'un premier aimant permanent, et tous les pôles saillants de l'autre partie palier magnétique se trouvant du côté de la partie moteur sont entourés d'une bobine pour un palier magnétique ou équipés d'un premier aimant permanent.
